OBJECTIVES: This study was carried out with a descriptive design to evaluate the performance, comprehensiveness, reliability, and quality of Turkish YouTube videos addressing ECT. METHODS: The Turkish keywords "Elektrokonvülsif Terapi, Elektrokonvülsif Tedavi" and EKT [Electroconvulsive Therapy, Electroconvulsive Treatment and ECT] were searched on September 15, 2023, and the first 30 for each keyword and total 90 YouTube videos were examined. A form developed by the researchers was used for comprehensiveness, DISCERN for reliability, and Global Quality Scale for quality. RESULTS: The videos' (N = 27) average "number of views" was 546881.3 ± 1754392.2, the average "comprehensiveness score" was 4.8 ± 3.0, the average "reliability score" was 3.1 ± 2.2, and the average "quality score" was 2.6 ± 1.5. When the videos were examined for reliability, 55.6% contained good and useful information for the audience, whereas only 33.3% were of high quality. There was a significant positive correlation between comprehensiveness, reliability, and quality (P = 0.000). CONCLUSIONS: People with psychiatric problems or their relatives resort to the Internet and platforms such as YouTube on topics for some information they are unfamiliar with, it is recommended that the content prepared in these areas be comprehensive, reliable, and of high quality.
